I'm designing my own case and I was wondering about power buttons. I'm not fussed about making my own, I'd be quite happy with a button I could buy from somewhere else and just stick in a hole in the case.

Is there any store online that sells power buttons? Preferably one with a wire so I can put it in the front of the case and attach it to the motherboard?

Thanks for the advice so far. I find a lot of these buttons will require me to do a bit of wiring myself. Isn't there something more complete that just needs to be plugged in? Quite hard to find since most cases have buttons in them I guess. :/

But a cheaper plugin-and-play option. Finding an all-in-one solution was something I wanted, though I thank you for your help and if I ever have the patience to make a standalone button myself I'll be sure to check back here.

Call up one of the computer repair stores in your region, they should have junkers out the back which they have not touched in a long time with all the wiring you need to make a custom build for next to nothing.
